Penholder.



IINE TA% AENT LOUIS STORCK, OF BROOKLYN, NEW YORK.

PENHOLIDEB.

Application filed May 12, 1917.

To all whom it may concern:

Be it known that I, Louis S'roncx, a citizen of the United States of America, residing at Brooklyn, Kings county, and State of New York, have invented certain new and useful Improvements in Penholders, of which the following is a full, clear, and exact description.

This invention relates to a device arranged to clamp a pen-point to a pen-holder, the object of my invention being to provide means whereby a pen-point can be easily applied to a pen-holder and as easily detached therefrom. It is a well known fact that through constant use and exposure to the air the ink will cause a pen-point and the holder to become fastened together, thereby making the extraction of the pen-point a diflicult operation and one that cannot al ways be performed without breaking either the pen or the holder. My improved device is arranged to obviate the above difliculty.

I will now proceed to describe my invention in detail and finally claim the essential features thereof, reference being had to the accompanying drawing, which forms part of this specification, wherein Figure 1 is a side view, partly in section, of a pen-holder embodying my improvement showing the clamping element in releasing position, the section being taken on a line 11 in Fig. 4;

Fig. 2 is a similar view showing pen secured by clamping element, the section being taken on a line 22 in Fig. 4;

Fig. 3 is a top plan view;

Fig. 1 is an enlarged cross sectional view, the section being taken on a line H in Fig. 1; and

Fig. 5 is an enlarged perspective View of one of the clamping elements.

In the drawing, the numeral 6 indicates a portion of a pen-holder which may be re duced at 6 to receive a ferrule 7, the said ferrule being cylindrical for the most part, but flattened at 7 for a purpose to be described.

My improved pen-point holding device comprises a lever 8 (in this instance a bellcrank lever) consisting of the handle portion 8 and cam-portion 8 arranged to cooperate with a yieldable plate or presserbar 9 preferably of spring metal, spring steel, for instance. The lever 8 is provided with trunnions lqadapted to engage seats 11 formed in the flattened portion 7 of the Specification of Letters Patent.

illustrated as clamped to the ferrule 7. The V v trunnions 10 are preferably formed integral wlth the lever 8. In other words, the lever 8, and its trunnions, are preferably struck out of the same material by a suitable forming element, such as a die.

It will be seen by referring to Fig. 4 that the lever 8 is dependent upon the presserbar or yieldable plate 9 for its maintenance 1n position in the seats or pockets 11. The inner end of the bar or plate 9 is held by the reduced part 6 of the holder 6 and is set thereinto at an angle relative to the axis of said holder in order that pressure can be exerted directly upon the trunnions 10, (Fig. 1) rather than upon the cam-portion 8 of the lever 8. The pressure of the bar or plate 9 holds the lever 8 in place, at the same time permitting it to be partly rotated in the direction of the arrow (Fig. 1) to force the free part of the bar or plate 9 downwardly and against the pen-point 13, as shown in Fig. 2, to firmly clamp same in place.

It will be seen that the free end 14 of the bar or plate 9 projects beyond the lever 8 or trunnions 10; hence, when the said plate is forced downwardly, as shown in Fig. 2, the said end 14:, will, when brought to bear upon the pen-point, yield and allow the cam-portion 8 to assume a vertical position, thereby firmly pressing the pen-point against the ferrule 7. When the lever S is finally forced to the position shown in Fig. 2, the cam-portion 8 thereof will assume a vertical position and jamb the end 14 of the bar or plate against the pen 13.

The flattening of the ferrule at 7 a permits of the formation of the pockets or seats 11, which are integral with the said ferrule and struck up therefrom, and also permits the portion 8 of the lever 8 to lie substantially in line with the cylindrical portion of the ferrule 7. The pen 13 can be readily removed when the portion 8 of the lever is raised to allow the plate 9 to spring upwardly or away from the pen-point.

It will be also seen that only a small portion of the outer surface 15 of the pen-point 13 contacts with the ferrule, the inner surface 16 of the pen being free from contact with any portion of the holder or ferrule proper.

The cutting away of the holder at 17 is an arbitrary means to facilitate the insertion of the handle into the ferrule.

ing in the Wall thereof, pockets located one.

on each side of said opening, a lever pivotally mounted in said pockets, a cam-portion carried by the lever located Within the ferrule, and a yieldable presser-bar Within the ferrule bearing against said lever arranged to be depressed and forced against the penpoint Within the ferrule by the cam-portion of said lever, said yieldable presser-bar acting at all times to retain said lever in position Within said pockets.

2. In combination With a pen-holder, a ferrule carried thereby to retain a pen point, said ferrule being flattened for a portion of its length and provided with an opening in said flattened portion, pockets carried by said flattened portion located one on each side of said opening, a lever pivotally mounted in said pockets, a cam-portion carried by the lever located Within the ferrule, and a yieldable resser-bar Within the ferrule bearing against said lever arranged to be depressed and forced against the penpoint Within the ferrule by the cam-portion of said lever, said yieldable presser-bar acting at all times to retain said lever in position Within said pockets.
